DATENÜBERTRAGUNG ZWISCHEN MODULEN

In a method for transferring data (D) between a first module ( 1 ) and a second module ( 2 ), data (D) can be transferred from a data memory ( 4 ) of the second module ( 2 ) to the first module ( 1 ) either in a secured or not secured manner. The time required for authentication (IV) is reduced by first transferring first data (D) in a not secured and then in a secured manner, wherein the data being used by means of a processor (CPU) of the first module ( 1 ) for a first process (III). The data (D) transferred in a not secured manner are compared with those transferred in a secured manner and if there is a difference, results from the first process (III) are discarded.
